So there you are, admiring your Coreopsis and suddenly you notice spots and holes--spots on the backs of two western spotted cucumber beetles, and holes cut in the petals.
Ah, there's two of them.
The beetles, about a fourth of an inch long, are fun to photograph, but they're not your buddies. Nor would they want to be!
"Cucumber beetles are very common pests in vegetable gardens and may also attack ripening stone fruit," says the UC Statewide Integrated Pest Management Program. "The most abundant species in California is the western spotted cucumber beetle, Diabrotica undecimpunctata...The western spotted cucumber beetle is greenish yellow and has twelve black spots on its back."
Ever counted the spots? Yes, 12.
We've seen the beetles feeding on the leaves of flowers and many vegetables. "Cucumber beetles may also spread cucumber mosaic virus or wilts in cucurbits," UC IPM says. "Larvae feed exclusively on roots, but do not generally damage garden plants, although corn may occasionally be damaged."
Spotted cucumber beetles don't move very fast early in the morning, so they're fairly easy to photograph.
And sometimes you get a "two-fer," two in the same image. 24 spots.

This was a non-replicated evaluation; therefore, no statistical analysis is presented (Table 1). Stand counts were made approximately two weeks after planting on April 9th. The stand was assessed as the number of plants per two-foot length. Twelve replicate counts were averaged. In early May, we observed that Sutter and advanced lines 102, 104, and 110 had slightly earlier flowering than UC 27 and advanced lines 94, 95, and 96 (Fig. 1). We are interested in knowing whether the advanced lines have tolerance to Fusarium wilt and Ascochyta blight, but no diseases were observed at this location.
We harvested on July 25th. The plots in their entirety were combined and weighed. At harvest, the grower observed that lines 104 and 110 had an upright growth habit that made them easier to harvest. We measured harvest moisture on three subsamples, which were averaged for the summary table below, and we evaluated 100-seed weight as a measure of seed size, averaging five subsamples. In previous evaluations of these advanced lines at UC Davis, they have had higher yield and larger seed size than the industry standard varieties, and that held true at the San Joaquin County site this year.
We would like to thank the cooperating grower and bean warehouse; the CA Crop Improvement Association for funding regional trials; and the CA Dry Bean Advisory Board for assistance with statewide research prioritization and assistance with outreach.

Event: AAIE Citrus Roundtable
Location: Lindcove REC, 22963 Carson Avenue, Exeter, CA
Date: August 20, 2024
Time 8:00 AM to 1 PM.
Register by following the link. Citrus Roundtable for SJV growers: This is an opportunity for citrus pest control advisors to get together and talk about how they manage pests.
The round table will discuss Ant Control, ACP, Thrips, Red Scale, Mealybug, Weed management, current regulations and pest management problems citrus pest control advisors have had. UCANR's Dr. Sandipa Gautam, Cooperative Extension Area Citrus IPM Advisor, David Haviland, Entomology and Pest Management Farm Advisor, Jorge Antonio Angeles, Weed Management Advisor, Dr. Bodil Cass, UCR Subtropical crops Specialist, and Chris Greer Assistant Ag Commissioner, Tulare County will be presenting at this meeting. The event will conclude with open discussions about research/extension needs in various sectors.
